At the same height, the maximum change in the distance of the maximum ink point is the gender. In the above average, the female average is A I11』9 cm. The other secondary cause is the angle of rotation of the pelvis. When the wheel is tilted forward, the distance of the maximum dust point can be reduced by about one degree, which is calculated by means of centimeters. The maximum pelvis rotation is reduced. When the angle is 60 degrees, the maximum pressure point distance is reduced by 2.3 cm. In the most common situation, when the normal bicycle is riding, the position of the handle is different, so that the rider (4) leans forward and causes the bone to tilt forward. However, the actual bicycle seat is convex, and the distance of the maximum pressure point should be calculated by the distance between the inner edge of the ischial tuberosity and the convex surface of the seat cushion. If the rotation of the pelvis is added, the maximum pressure point distance of the ischial bone should be smaller than the maximum pressure point of the above plane when the actual seat (four) is multiplied. 5〜9. 5厘米。 The distance of the lateral value of the sacral sac. The variability of the rotation of the pelvis and the deformation of the different cushions will result in a situation where the maximum pressure point distance cannot be accurately defined. In fact, in addition to the above main causes, many studies have also shown that different ride loads can also cause changes in pressure distribution. It can be seen that 'the pressure distribution caused by the actual dynamic riding condition is very complicated'. When designing the bicycle seat, it is impossible to design the U and seat (four) type, the strength is difficult and the material f is selected with a clear and fixed size. There is a considerable relationship). Therefore, it is necessary to have a large area (ZQne) material design record contact area = to include the maximum possible variation. But in fact, the county's need for the seat 2 is not only the main consideration due to the variation of the pressure distribution. However, (4) distribution and Shuza, and even the health of the rider have a direct _ sex, due to double considerations and research. County M, the quality requirements of the seat cushion, in addition to the pressure configuration (user health), also include the constraints of ventilation and heat dissipation. It is expected to be lighter, and the cost of the external and secret costs is secondary. 201231338 It is indeed very difficult to achieve the design of the seat cushion that meets the above requirements at the same time. In the shape cushion of many shapes on the existing market, it is attempted to qualitatively arrange on the seat cushion with different supporting (softness) heterogeneous materials, and the pressure distribution of the control part is obtained by changing the shape curve of the control part. The results are only able to meet the single or limited function, and it is difficult to combine the requirements of the above-mentioned generalized seat cushion. Even sacrificed for comfort - some other importance such as the stability of the time support « then hooked and comfortable cushion design, often part of the seat cushion in the center, face open ((3) Bu Yu ut) or even Remove the front (rear) end of the seat cushion, only retain the bone nodule contact (four) design, these can only solve the smaller range of questions 2 'the other common seat cushion middle part, with extremely soft material f or supplemented with air cushion, soft Net 4 'under the non-dynamic or extreme tilt (four) degree wire, or can solve some of the problem of (4), but when the riding strength increases, due to the variation of the seat of the various riders, the friction will be insufficient due to the support. Sliding occurs, resulting in (four) ΐ + reduced bodyiness, which affects ride control and reduces riding. If it is supplemented by the personal custom seat cushion design, it can be solved, but its economy and versatility are not good. I bicycle seat cushions often form a sharper convex surface due to the pressure of the rider's weight, and force the rider to contact the seat to force the outward movement of the joint, while the ischial tuberosity and In the case of the nucleus of the ear, the genital area of the genital area is likely to cause damage to the rider (c) (10) endalnerve, or due to the genital area. Numb 201231338 and ischemia, the formation of sexual dysfunction or even the damage of the reproductive system. On a general planar seating surface, blood vessels and a large number of nerves in the genital area are subject to constant compression. If the seat surface is the same as the convex shape of the common bicycle seat, the degree of compression and the adverse effect on the human tissue are relatively greater. When the support is not good after the seat cushion, the force will not only increase the above trend, but also form the front end of the seat cushion, which is relatively upturned, and increases the pressure on the genital organs of the rider. Accordingly, the present invention is intended to obviate or at least alleviate the problems encountered in the prior art. [SUMMARY OF THE INVENTION The technical problem to be solved by the present invention is to provide a bicycle seat cushion capable of releasing pressure in view of the deficiencies of the prior art.

The ritual and * gap can be directional according to the demand (4) the size and the degree of the cut surface, into the 201231338 = excellent stability of the friction to increase ride control, and apply to the ... strength of the various ... When the air flows through the seat area below the seating area during riding, H = convection, providing excellent ventilation and heat dissipation comfort through the gap between the sides. The fifth technical means to be improved according to the present invention is that the seat surface area can provide a contact surface which is close enough to the buttocks in a dynamic manner when the seating area is relatively soft, and further provides sufficient friction to maintain the friction when the partial pressure is lowered. Improve stability and ride control. The sixth technical means for improvement of the present invention is that the pressure of blood vessels and a large number of nerves in the reproductive area can be greatly reduced and sufficient support can be provided. The seventh technical method to be improved according to the present invention is that, in addition to the large depression near the maximum pressure of the left and right ischial bone nodules, the seating area surrounding the seating area is a planar concave or micro convex surface, and the edge area The outline becomes small. The eighth technical improvement of the present invention is that the edge area is softer than the seating area, and the seating area provides a soft and soft effect for the occupant to ride comfortably. It is felt that the material of the edge zone is hard, and the material selected in the edge zone has the characteristics of toughness and high rigidity to withstand the acceleration of gravity and fatigue stress. The seating area provides better seating comfort and provides better structural strength. The seating area and the edge area can be of different colors to increase the appearance of the product. Moreover, the seating area and the edge area can be mass-produced in a modular manner, and the development cost can be reduced by using two sets of upper molds and combinations to create more combinations.
